Missed signal in FusedPrintersLoader.

1. In the FusedPrintersLoader we start observing the printers on
   the device and if they change we send the result. If however,
   the printers are already loaded in our session (because it
   joined an ongoing printer discovery) and the pritners do not
   change, the loader never sends its result. Now we are registring
   the callback only after historical printers are loaded. We
   also immediately check after starting discovery whether the
   there are printers in the discovery session and if so deliver
   them.

2. Improved logging in the FusedPrintersLoader.

PackageManager#queryIntentServices breaks its contract.

PackageManager#queryIntentServices javadoc contract states that this
method (and the like) never returns null, rather an empty list if
no result is found. However, there is a path in the PackageManagerService
that returns null, thus breaking the contract. Handling the null list
explicitly.

Remove unused views when we return to keyguard

This fixes a bug where launching the camera would move
the camera view to the root hierarchy.  In insecure mode, a
subsequent dismiss() comes in and tears down the view hierachy
before the event can be processed, which left the view in the
root hierarchy.

The fix is to remove all children when we reconstruct keyguard.

Add gravity settings to PopupWindow/ListPopupWindow/PopupMenu

Allow calling code to specify left/right/start/end gravity when
showing a popup attached to an anchor. This allows easy alignment of
either the right or left edges of the popup and anchor view.

Fix for Text fading on RTL app names is done at the beginning...

This is a fix for bug 10918591 [Android][bidid][HH] "Text fading on RTL
app names is done at the beginning of the text, not at the end."

The old logic for getting the fade edge was not symmetric with respect
to the text direction - when the text was centered, it basically
always placed the fade edge at the left, which of course is appropriate
for LTR text but not RTL. This patch makes the two paths symmetric
and sensitive to text direction.

Dismiss keyguard when resuming visible activities

If an activity is visible behind the keyguard when it is launched
by another activity then there would be no call to dismissKeyguard.
Because the other activity is pausing the call to dismissKeyguard
is skipped in startActivityLocked(). And because it is already
visible the call to ActivityRecord.windowsVisible() is never made and
the call to reportActivityVisibleLocked() which calls
dismissKeyguard() is also never made.

This change recognizes when an activity is resumed and visible and
calls dismissKeyguard() in that case.

Fixes bug 10732489.
